IMPROVEMENT IN MECHANISMS FOR MOVING GRAIN IN THE SACK.

Specification forming part of Letters Patent No. 152,753, dated July 7,1874; application filed May 15, 1874.

To all whom it may concern:

Be it known that we, E. P. KENYON, JAMES J. MOGL BBEN, and J oHN H.OLLRIGH, of Milton, Galaveras county, State of California, have inventeda Derrick for Moving Grain- Sacks and we do hereby declare the followingdescription and accompanying drawings are sufficient to enable anyperson skilled in the art or science to which it most nearly appertainsto make and use our said invention without further invention orexperiment.

Our invention relates td an improved device which is to be used in,handling grain in sacks; and it consists in the combination of a mainand a supplemental boom, the main boom swinging a vertical mast, and thesupplemental boom being attached to the main boom, both being worked byropes and pulleys. The grappling-fork is suspended from the boom andgrasps the sack, transferring it to any point desired.

Referring to the accompanying drawings for a morecomplete explanation ofour invention, Figure 1 is a perspective view of our device.

A is a triangular or other suitably-shaped base, having the mast B,which is steadied by guy-ropes. The boom 0 has its inner end attached tothe mast by means of a clasp, D, which allows it to swing around fromside to side. At the outer end of this boom a supplemental boom, E, ispivoted through some point in its middle section, so that it will have amovement about this point of support. The pulley-blocks F and G aresecured, respeotively, to the mast-head and to the end of the boom 0;and a rope, H, leading over them, and thence down to the ground, servesto raise and lower this boom. Near its inner end an arm or bar, I, isclamped securely to the boom 0, and nearly at right angles with it. The

lower end of this bar is provided with a pulley, J, over which the ropeK leads, and is fastened to the inner end of the supplemental boom E. Bythis rope the boom E is raised and lowered independently of any movementof the boom 0. Our device for handling the sacks consists of the curvedarms L, hinged together, as shown at m. At their lower ends these armsare provided with cross bars or strips N, which serve to grasp and holdthe sack until it can be deposited at the desired point.

By this construction of the two booms, workin g upon each other, and atthe same time independently, together with our fork or device forseizing the sacks, we are enabled to remove the sacks from athrashing-machine and pile them in any suitable or desired place.

Having thus described our invention, what we claim, and desire to secureby Letters Patcut, is--- 1. The derrick consisting of the mast B, withthe main boom 0 and the supplemental boom E, connected as shown, andprovided with the pulleys F, G, and J, with their operating-ropes,substantially as and for the purpose herein described.

2. The device for lifting and moving sacks, consisting of the curvedarms L, united at m, and provided with the cross-bars N, substantiallyas and for the purpose described.

In witness whereof weherennto set our hands and seals.
